• LTC4366 with parallel FETs?

    I'm designing a new circuit with the LTC4366 and having trouble finding a suitable, in-stock FET that can meet my SOA needs during a surge.  Is it possible to use two FETs in parallel with this device?  During normal (non-surge) operation will they…

  • RE: LTC4366 VDD and SD voltage

    Hello Kazu,  It is normal. The VDD absolute maximum voltage rating is to prevent a >10V external supply being connected directly across VDD and VSS without any current limiting resistor and destroying the ~12V (typical) internal clamps. When external current…

  • LTC4366-2 RLC Ratings for High Voltage Application

    Hi

    I'm planning to use below circuit for 360V 14A application for surge protection.

    Here i would like to know what should be the ratings required RLC components for safe operation. For example , power ratings for Rg, Cg, Rin, Rss, C1 , RFb etc

  • RE: LTC4366 not functionnal

    Hello,

    Sorry for the delay...

    We have make some progress in the resolution of the problem (mismatch in the PCB footprint) but we still have a wrong behavior.

    The board is now functionnal with input voltage lower than 20V. When input voltage is higher…

  • LTC4366-2 Simulation

    I just downloaded the LTC4366-2 simulation model from online and simulated the same.

    As per circuit the IC should operate in Regulated Mode when Input voltage is greater than 18V. To check this I set Input voltage as DC 19V and Run the simulation.

    But…

  • Bypass Diode for LTC4366-2 Surge Stopper

    I am using the LTC4366-2 surge stopper in a MIL-STD-1275 application, and have added Rs to mitigate output short circuits. In simulation, I have modelled the circuit both with and without Dbypass and cannot determine what role it is playing in the circuit…

  • RE: LTC4366 at high voltage.

    The image is not clear but here are some debug suggestions: A capacitor on the FB pin is not required by the datasheet. It will slow down the LTC4366 response, possibly allowing the output to exceed the clamp. If LTC4366 is getting damaged, its absolute…

  • LTC4366-2 High current with low supply voltage

    Hello,

    I have a question to LTC4366-2. Is it possible create design for 24V supply voltage, 15A max consumption of load, which will be worked from 10V and maximum surge is short pulse 250V.  (For military standard 1275)?

    When i respect SOA of MOSFET i…

  • LTC4366-2 dont work

    Hi! I developed simple surge stopper circuit using LTC4366-2, but it doesnt work on the pcb, althouht it was working properly in LTSpice simulator. What is the problem? Also, i noticed that circuit started up when i toched the floating ground point of…
